I just encountered what looks like the same issue. Worked with OpenBSD v4.4, has
been working since OpenBSD v3.2. I will try some of the suggestions.

I also noticed that the /dev/drm0 is being removed, and then complaining it's
not there any longer. Running MAKEDEV recreates /dev/drm0.

Attached is a dmesg and Xorg.0.log, any news or progress please let me know.

Regards

Nigel Taylor
